MMASU063SCG6R2DFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG6R2DFNA01 is a 6.2 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 0201 (0603 Metric) form factor and is designed for medical and non-critical applications. The part maintains an Active product status with full RoHS3 compliance and MSL 1 moisture sensitivity rating.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements shift toward alternative certifications such as automotive-grade qualifications. The substitute identified for this capacitor maintains electrical and mechanical compatibility while offering different product lifecycle positioning and application focus.

Substitute Part Grouping Explanation

Substitution logic for the MMASU063SCG6R2DFNA01 is based on strict electrical and mechanical parameter matching. The identified substitute part UMK063CG6R2DTHF maintains compatibility through the following criteria:

Electrical Parameters (Must Match):

• Capacitance value: 6.2 pF
• Tolerance: ±0.5pF
• Voltage rating: 50V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Package type: 0201 (0603 Metric)
• Mounting method: Surface Mount, MLCC
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum thickness: 0.013" (0.33mm)

Compliance Parameters (Must Maintain or Improve):

• RoHS3 compliance status
• MSL 1 rating (Unlimited moisture sensitivity)

The substitute part differs in product lifecycle status (Not For New Designs versus Active) and includes automotive-grade AEC-Q200 certification, positioning it for different application contexts while maintaining full electrical and mechanical interchangeability.

Engineering Selection Recommendations

Primary Part Selection (MMASU063SCG6R2DFNA01): Select the MMASU063SCG6R2DFNA01 for new designs requiring active product status with ongoing manufacturer support. This part is appropriate for medical and non-critical applications where long-term availability and design continuity are priorities. Active product status ensures consistent supply chain access and manufacturing process stability.

Substitute Part Selection (UMK063CG6R2DTHF): The UMK063CG6R2DTHF serves as a direct electrical and mechanical substitute when the primary part is unavailable. This substitute is suitable for existing designs requiring component replacement or for applications where automotive-grade AEC-Q200 certification adds value. However, the "Not For New Designs" status indicates this part is in end-of-life phase; use only for legacy system support or when automotive qualification is a specific requirement.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL 1 ratings, ensuring environmental and moisture-handling compatibility. The substitute's AEC-Q200 certification provides automotive-grade reliability assurance, making it suitable for automotive and industrial applications where enhanced qualification is beneficial.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG6R2DTHF be used as a direct replacement for MMASU063SCG6R2DFNA01?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (6.2 pF), tolerance (±0.5pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and package form factor (0201/0603 Metric). They are pin-compatible and footprint-compatible for PCB assembly.

Q: What is the significance of the "Not For New Designs" status on the substitute part?

A: This designation indicates the UMK063CG6R2DTHF is in end-of-life phase and the manufacturer is not recommending it for new product development. It remains available for existing design support and legacy system maintenance. For new designs, the MMASU063SCG6R2DFNA01 (Active status) is the appropriate choice.

Q: Does the AEC-Q200 certification on the substitute part affect compatibility?

A: No. AEC-Q200 is an additional automotive-grade qualification that does not alter electrical or mechanical performance. It represents enhanced reliability testing and is a superset of standard requirements. The substitute remains fully compatible with the primary part's specifications.

Q: Are there any application restrictions when using the substitute part?

A: The substitute part is qualified for automotive and SMPS filtering applications, while the primary part targets medical and non-critical applications. Both parts meet the same electrical and environmental specifications. Application suitability depends on your specific circuit requirements and industry standards, not on the parts' technical compatibility.

Q: What is the moisture sensitivity difference between these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. They can be stored and handled under standard conditions without special moisture control measures.

Q: Can these parts be mixed in the same production batch?

A: Yes, from an electrical and mechanical standpoint. However, design documentation and traceability records should clearly identify which part number is used in each unit, as they have different manufacturer part numbers, product statuses, and certifications.
